Bug 115893

Summary: ffmpeg-2007.07.12_3 graphics/php5-ffmpeg 0.5.0_2 --> libavcodec.so.1: Undefined symbol pthread_join in Unknown on line 0

Description Andy Hilker 2007-08-28 10:00:06 UTC 
The php4-ffmpeg and php5-ffmpeg module used by apache20/php is broken.
It seems to be a pthread problem with ports/multimedia/ffmpeg.

Compile ports/multimedia/ffmpeg without -pthread or using ffmpeg-2007.05.30_1 still works.

httpd-error.log gives:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20060613/ffmpeg.so' - /usr/local/lib/libavcodec.so.1: Undefined symbol &quot;pthread_join&quot; in Un
known on line 0
[notice] Apache/2.0.59 (FreeBSD) PHP/5.2.3 with Suhosin-Patch mod_ssl/2.0.59 OpenSSL/0.9.8e configured -- resuming normal operations

Fix: 

Not a fix, maybe only a workaround or debug hint:

Compile ports/multimedia/ffmpeg without -pthread or using ffmpeg-2007.05.30_1 still works.
How-To-Repeat: cd /usr/ports/graphics/php5-ffmpeg
make install clean
(will install ports/multimedia/ffmpeg as a dependencie)
(same error with php4)

/usr/local/etc/rc.d/apache2.sh restart

will lead to an error in httpd-error.log:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20060613/ffmpeg.so' - /usr/local/lib/libavcodec.so.1: Undefined symbol &quot;pthread_join&quot; in Un

How do I do this?

Edit the Makefile for the ffmpeg port and remove the --enable-pthreads
flag.  But I am not sure about unwanted effects of this "workaround".

unwanted effects of this "workaround".??

What do you mean by this?

I have the same problem. Any idea when it will be fixed?
Comment 6 ahilker 2008-02-22 14:04:02 UTC 
Found under http://groups.google.com/group/ffmpeg-php/ (topic:
Success compiling ffmpeg-php on freebsd ), tried and worked. Find
the patch for /usr/ports/graphics/php4-ffmpeg/Makefile below.

Sorry, the last provided patch will trigger the "segfault on kill -HUP"
problem described in PR ports/120409.

The before described workaround by removing "--enable-pthreads" from
/usr/ports/multimedia/ffmpeg/Makefile still works.
